RADIATOR CA]? DEVICE.

Application filed January 12, 1923. Serial No. 612,215.

i now used for automobile radiators is not only ornamental and capable of being opened and closed, but it is the means of support for the moto-meter device. Such -improved form of radiator cap, besides being very practicable, is attractive, and of specific value as an accessory to any type or class of automobile- To guard against the detaching or the removal of the radiator cap-device by unauthorized'persons, it is desirable that the device may be-rigidly locked or secured at its position.

To provide a cap-device of rugged and durable construction and which said device I when secured to the'radiator nozzle becomes locked thereon, is the object of the present invention.

,The objects of my'invention are accomthe new and improved c0nstruction, comb-i nation and arrangement of parts, shown in the accompanying drawings. 'Theseveral parts of the invention are identified by suit able characters of reference applied thereto in the different views in the which Figure 1 is afrontview of my improved radiator cap-device, a portion thereof being broken away and shown in crosssection.

Figure 2 is a top plan view of Figure 1, a portion of the cover-plate being broken away. I

Figur 3 is an end view taken in the di+ rectio-n' indicated by the arrow 3 in Figure1.'.

' .Figure 4: is a vertical central sectional view taken on the, line 4-4 in Figur 2.

Figure 5 is a sectional view taken on the line 5-5'in Figure2. p My improved radiator cap-device comprises a metal body-piece A provided with the usual bore which issuitably threaded to be screwed down on the-standard type of radiator nozzle 1. I

1 The said body piece .isprovided with an plished by and theinvention is. embodied in,

'- adapted to be connected to the said body internal annular shoulder which has the beveled annular face A and the annularfiat seat A Adapted to rest on the seat A is a gasketor pack ring B which maybe made of rubber or of a leather composition. Hingedly connected to the integrally" formed lug A (see Figure 4) is a metal cover. plate C, which may be ofthe contour shown in the top plan view in Figure 2. Formed integral with the underside of this cover plate is a seat C which registers with and makes close contact with the pack rin when the plate is disposed at the lowered or closed position.

This cover plate constitutes aclosure element for the body-piece, and a support for the moto meter device D which is suitably secured by a usual bolted and sealed connection. At the forward portion of the cover plate is the integrallyformed tongue C (see Figure 2.)fwhich registers: with a boss A formed integrally on the body piece. A transverse recess or opening C is formed in said tongue." Disposedin a recess G in the upperportion of boss Ais a threaded stem E whose lower end is journaled on the cross pin E. On the stem E is the burrF. The stem E when swung up to the vertical position occupies'the opening C of; the cover plate the burr F the cover plate is pressed downwardlyand is retained securely at sealed contact with the said pack ring. My invention comprises means to, fasten the body piece to the radiatornozzle, and a device piece to close' the opening or recess in which the said fastening means is. contained, and wh1ch said dev1ce becomes lockedwhen it is placed at connected position."

The combination, form, and .detailof the several parts for carrying my invention to said set screw H inwardly-until it has tightly engaged the threaded nozzle 1.

Ad to 2f ed to be screwed in thesaid bore and By then screwing down I Any suitable form of socket wrench may beused to turn or drive the.

ose it so as to prevent" unauthorized access to the set screw H, is a. threaded closure stud J. This stud J is provided with a plate-like head K which may be oi the form and may have a monogram initial or fanciful adornment, as shown in Figure 1.

Near the end of the said stud J is a diametrically disposed recess J of suitable depth substantially as shown in Figure 4. Adapted to be disposed in this recess is a slug L. Extending downwardly from bore A is a well A so located with reference to the set screw H that when the said set screw will have been screwed into the set position at imbedded contact with the nozzle 1, as shown in Figure a; the said well has been passed and is in the clear as shown in Figure 4. Thus, the cap device is secured to the nozzle of the radiator. Before starting the stud J into the bore A the slug L is inserted into the recess J lVhen the stud J will have been screwed into the position shown, the slug L will have dropped in the well as above described. The stud J is then immovable. Force applied to the head plate K may break off the plate, but with the stud J held by the slug L, the stud is incapable of being removed from the bore, and itconstitutes a locked guard against access to the set screw H.

It is apparent that the radiator cap-device so fastened, is secured against theft.

Access to the radiator nozzle for the purpose of introducing water to the radiator, is easily had by unscrewing the burr F and swinging down the stem E. The cover plate may be swung on its hinge to full open position. Occasion or necessity ever to detach the body-piece "from the radiator nozzle, for any purpose, is remote. However, in case of necessity for detachment or re moval of the body-piece, the radiator may be disconnected from its fastenings, and

'moved to inverted position, causing the slug L to slip or drop from the well A, and which permits the stud J to be easily unscrewed and removed. It is obviouslythen an easy matter to apply the socket wrench to and retract the set screw H. While the embodiment of my invention, as above described, is of the preferred form, it is understood that minor changes may be made in the structure and arrangement and detail of the several parts of my improved cap-device, within the scope of the invention as defined by the appended claims, without in the least departing from the nature or spirit of my invention.
